SAFETY RAZOR Richard Roberts, Freeport, N. Y. application August 7, 1944', Serial No. 548,405

a Claims. (01.30am

This invention relates to aniimprovement in safety razors. j

One of the featuresof the invention consists in the provision of a lengthwise fol'dable razor handle'that in folded condition provides a corn nection at one end thereof that engages the blade holder of a razor;

Still a further feature of the invention is rovided in the formation-pf a shaving instrument handle that folds transversely-of its length to it within a match book folder.-

Another feature of the invention resides in the provision-"of a blade holder having interfitting tongue and hole parts that form a slot therebctweenadapted to receive one end of a handle to hold the parts in connected relation.

Other features and structural details of the invention will be apparent from the following description when read in relation to the accompanying drawings wherein:

Fig. 1 is a front view of a shaving kit that con tains the improved razor.

Fig. 2 is an end view of the kit shown in Fig. 1.

Fig. 3 is a front view of the kit showing the front cover thereof folded to an open position.

Fig. 4 is a view similar to Fig. 3 with the improved razor handle therein formed to an open position.

Fig. 6 is a detail view of the handle of the safety razor showing the same in unfolded condition.

Figs. '7 and 8 are detail views showing the razor handle folded along its lengthwise dimension.

Fig. 9. is a side elevation showing the parts of the safety razor assembled for use.

Fig. 10 is a detail front view of the blade holder of the improved safety razor.

Fig. 11 is an. exploded view showing the detail parts of the blade holder illustrated in Fig. 10.

Fig. 12 is a view similar to Fig. 11 illustrating a modified form of blade holder, and

Fig. 13 is a detail bottom view of one of the parts of the blade holder illustrated in Fig. 12.

With reference to Figs. 1 to 5 of the drawings, the safety razor of the present invention is shown in connection with a cardboard folder having front and rear walls indicated respectively at 29 and 2 I. The folder is of conventional match book construction except for the provision of an insert 22 in the base thereof shaped in the form of a triangle. The insert is connected to the folder by staples or other suitable means with the tapering part thereof extending upwardly beyond the edge; of. the bottom part of the front wall 20. The folder closes in a: conventional: manner, the

razor blade holder and handle.

With reference to. Figs. 2, f, 1.0 and; 11,v a razor as steel. As: shown in Fig. 2, the projecting pieces of the part 2.1 extend-through the holes 25 in. the part: 24 when. the holder is assembled. The interfitted tongue and hole parts form a. v-shaped socket, one of whose walls is defined by the inside wall of the part 24. The other-ofthewalls of the socket is defined by the inside faces of the end walls 29 of the part 21 of the holder. The position of the holder within the kit is shown in Figs. 2 and 4. The sides of the socket are shaped to As hereinafter described, the mounting socket for the holder in the kit also receives the handle of the instrument.

Part 24 of the holder includes a guard 30. A fiat razor blade 3| having spaced slots 32 therein is positioned between the respective parts of the holder. In the showing in Fig. 11, the part 21 includes spaced projections 33 adapted to fit the slots 32 in the blade. In order to mount the blade on part 21, the spacing between the projections 33 is made slightly less than the spacing between the slots 32. Due to the fiexure in the flexible blade 3! when these parts are interfitted,

- the blade 3| is held in position on the part 21 with sufficient firmness to prevent the same from falling off in the absence of the part 24. When the parts are attached, the blade 3| is held therebetween. Projections 33 of the part 21 then extend through the slots 34 in the part 24.

The handle of the safety razor is indicated at its lengthwise dimension at the scoring lines 31 and along its transverse dimension to assume the form in which it is shown in Figs. 7 and 8. When so folded the approximately trihedral shaped end of the handle is inserted in the socket in the razor holder, the position in which it is illustrated in Fig. 9. The curved surface 38 of the handle is pressed flat against the part 24 of the holder so that the handle is tightly engaged in the handle receiving socket hereinbefore described in connection with the insert 22 of the kit.

To make the kit complete, a small tube 39 of shaving cream may be suitably secured to the handle 35 in the position for the same shown in Figs. 2 and 4.

In the modification of the invention shown in Figs. 12 and 13, the razor holder includes a part 40 having spaced projections 4| thereon adapted to receive the flexible blade 42. In this construction, slots 43 are provided at the respective ends of the blade, the same engaging the projections 4| and fitting therebetween under flexure to retain position on the part 40. To accommodate the projections 4|, the part 44 of the holder is also provided with suitable slots 45.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained. in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

What is claimed is:

1. A safety razor having a blade holder with a handle receiving slot therein, and a lengthwise and transversely foldable handle that in folded condition provides an approximate trihedral connection at one end thereof adapted to engage the socket in said'holder.

2. A safety razor handle foldable along its length and width that in folded condition is shaped in the form of an approximate trihedron at one of the ends thereof.

3. A safety razor handle formed of a substantially rectangular fiat piece of pliable material scored lengthwise and transversely to fold to a tapering body having an approximate trihedral shape at one of the ends thereof, said fiat piece also being scored transversely of its length to fold to a U-shape.

4. In a safety razor, a flexible blade having slots in the end portions thereof, a holder for said blade having spaced projections thereon fitting said slots, the spacing between said projections being slightly less than the spacing between said slots to retain said blade on said holder due to the flexure in said blade.

5. A safety razor having a blade holder with interfitting tongue and hole parts formed to provide a socket, one of whose walls is defined by the tongue part and the other of whose walls is defined by the hole part, and ahandle having one end thereof fitting between the parts defining said socket to retain the same in position on said blade holder.

6. A razor as claimed in claim 5, in which said socket i V-shaped.

7. A razor as claimed in claim 5, in which the socket fitting end of said handle is shaped in the form of an approximate trihedron.

8. A safety razor having a blade holder with a V-shaped socket therein, and a handle with lengthwise and transverse folding lines that in folded condition provides a portion at one end thereof with flared sides adapted to fit said socket.

9. A razor as claimed in claim 8, in which said handle is formed of cardboard.
